HMAS Tolga was an auxiliary minesweeper which served in the Royal Australian Navy (RAN) during World War II.

Tolga was built in 1925 by the Walsh Island Dockyard & Engineering Works, Newcastle for Dorman Long, Sydney as Dorlonco.

She was utilised along the Queensland coast as a sugar lighter between shore to larger vessels offshore.

Surveys determined that she had deteriorated and was structurally unsafe to transport back to Australia.

Tolga was towed out to sea by the frigate HMAS Condamine on 30 April 1946 and was scuttled off the north coast of New Guinea.
